Actually, at SF great america, there is another version:
V2 they are different because the one in marine world has a 45* angle with the twist. thats becuase the city impossed a limit on the coaster that it couldnt be more than 150 ft. tall, so they had to modify it from the original 186 ft. version by making the 90* angle 45*.
Edit: Angry Gumball is correct in his ride because he stated it was V2: Verital Velociy
2002, which is when it was modified. Therefor, i think that since he stated that it was the 2002 version, the rating should be changed. It was an honest mistake made by goliath, i never even knew that there was a different version till it came out, thats when i read about the change.
